Weighted delta is the raw difference times the criterion weight, so the 5 figures above sum to -0.7 — the difference between the two totals before either is rounded. Shares are of 1.3 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads 0 beside that -0.7.
